Comment 24 for bug 185190

I would say that this issue will lead to embarrassing negative publicity, because it is common with neighboring countries to have some sort of animosity; seeing the timezone of some other country when you select your city is going to be bad.

What I recommend is to disable the auto-calculation of the timezone based on proximity of the city. The user would have to pick the timezone on her own. In usability terms it is cumbersome, but I find it as an easy quick-fix.
